The state government provides age and sex population projections at several levels:
The projections are updated every five years following the release of final figures from the most recent Census of Population and Housing published by the Australian Bureau of Statistics (ABS).
These population projections comprise three series (high, medium and low). They reflect the likely range of population futures for South Australia and its statistical divisions. The medium series is the likely outcome at the time of publication, while the high and low series enable management of risks if a population trend that is higher or lower than the medium series emerges.
The factsheet (PDF, 245 KB) summarises projected population and demographic change for South Australia.
The report on Population projections for South Australia and statistical divisions 2011-2041 (PDF, 2122 KB) summarises the assumptions used to develop the projections and outlines the demographic context of the projection outcomes and their demographic significance.
The projections are based on the 2011 Census of Population and Housing and supersede those published in 2010. The South Australian Cabinet approved the projections and endorsed their use by State agencies on 10 August 2015.
Age by sex projections are produced for the 127 statistical local areas, 70 local government areas and 12 South Australian government regions in the State. They are aggregated by five-year age groups for five-year intervals over the period 2011-2031. Because of the inherent uncertainties in small area projections, it is not appropriate to project beyond a 20-year horizon.
Users of these projections should carefully read the explanatory notes (PDF, 22 KB) before downloading the projections.
Local area projections are also available to view in Location SA Map Viewer:

The following table contains a subset of the population projections by Local Government Area and links to infographics. The full set of projections (age by sex by five-year intervals) are available in the Excel workbook above. Users should refer to the explanatory notes (PDF, 22 KB) before using these projections.
Population projections are not forecasts of the future. They are estimates of the future size, age structure and geographic distribution of populations based on particular assumptions about future fertility, mortality and migration. Actual future populations will vary from these projections.
According to the Australian Bureau of Statistics, the preliminary estimated resident population (ERP) of South Australia at 31 December 2016 was 1,716,966 people. This is an increase of 10,300 people since 31 December 2015 and an annual growth rate of 0.6%. Australia’s growth rate over the same period was 1.6%.
Population growth is driven by natural increase (births minus deaths) and net migration (overseas and interstate). Net migration contributed 29% of South Australia’s population growth in the 12 months to December 2016. Positive net overseas migration helped to counter South Australia’s net interstate population losses.
South Australia's components of growth, 2015-16
Year ended 31 December 2016
Note: Population for this period is based on the 2016 ABS Census.The ABS do not adjust the components of growth. Therefore, the total population growth does not correspond to the sum of the components of growth.
More information is available from Australian Demographic Statistics - ABS catalogue 3101.0 and the Department of the Premier and Cabinet's Population Estimates Brief.
The latest available Australian Bureau of Statistics’ population estimates for local areas indicate that 1,429,122 people were living in the Greater Adelaide Planning Region as at 30 June 2016, accounting for 83% of South Australia’s population.*
In the 12 months to 30 June 2016 the Greater Adelaide Planning Region population increased by 11,358 persons which is a growth rate of 0.8%. Over the same period, Regional SA decreased by 147 persons to a total population of 283,932.
Of the Local Government Areas within the Greater Adelaide Planning Region, Onkaparinga (169,073) has the largest population, followed by Salisbury (140,906).
In the 12 months to 30 June 2016 Yankalilla recorded the highest growth rate (3.4%), while the combined Local Government Areas of Salisbury, Playford and Port Adelaide Enfield accounted for 39% (4,382) of the Greater Adelaide Planning Region's actual population growth.
Mount Gambier has the largest population of the regional Local Government Areas (26,993) and experienced a slight increase of 101 persons in the 12 months to 30 June 2016. Whyalla’s population declined by 174 persons over the same period. At 2.2% Lower Eyre Peninsula which contains the towns of Cummins and Coffin Bay had the highest annual population growth rate. See interactive graphs below.
The population of South Australia continues to grow and its composition is ever changing. In the five year period between 2011 and 2016, South Australia’s population increased from 1.64 million to 1.71 million, at an average of 14,688 persons per year.
The population change webpage provides a concise overview of recent population change and demographic trends in South Australia. It also provides important contextual information about South Australia and its regions, and is used in the development of population projections. A summarised version of the population change webpage is also available as an infographic.
The Workplace Atlas Report (PDF, 8396 KB) provides an overview of the nature and geographic distribution of employment in Adelaide. It contains useful maps, graphs, statistics and commentary that identify the locations of employment and describe the characteristics of the people employed in those locations.
The data used in the report is sourced from the 2006 Census of Population and Housing published by the Australian Bureau of Statistics (ABS). The study area is the Adelaide Statistical Division, which extends to Gawler in the north, Aldinga in the south and Mount Barker in the east.
Due to ABS 2011 Census Place of Work data quality issues the workplace atlas report and atlas have not been updated with 2011 data.
The interactive workplace atlas is a web-based program that allows users to explore a variety of themes related to employment in Greater Adelaide. It is based on the 2006 Census data but allows a broader range of data to be presented on the entire Greater Adelaide region. The data can be interactively mapped and graphed at different geographic levels, such as destination zones, statistical local areas, local government areas, state government regions and statistical divisions.
The themes featured in the atlas include:
To access and use the atlas:
Australian Bureau of Statistics data has been used to create detailed maps outlining how people in Adelaide travel to work. While the maps use data from a previous census (2001), current travel patterns are still similar.
The maps show:
Age and sex breakdowns of the data and method of travel are also provided:
